Improved efficiency of electrodeposited p-CuO/n-Cu2O heterojunction solar cell

Jayathilaka, Charith; Kapaklis, Vassilios; Siripala, Withana; Jayanetti, J. K. D. S. (2015)

We report electrodeposition of n-type cuprous oxide (Cu2O) films on p-type CuO films electrodeposited on Ti substrates for forming p-CuO/n-Cu2O heterostructures. X-ray diffraction (XRD) and scanning electron microscopy ...
Electrodeposited n-type cuprous oxide cubic nanostructures for liquefied petroleum gas sensing

Jayasingha, J. L. K.; Jayathilaka, K.M.D.C.; Gunewardene, M. S.; Dissanayake, D.P.; Jayanetti, J. K. D. S. (2016)

A surfactant free template assisted electrodeposition method was used to fabricate thick n-type Cu2O films having cubic nanostructures for the detection of liquefied petroleum (LP) gas at low concentrations. Templates ...
Surface properties of sulphur based surface modified n-Cu2O thin films for enhanced liquefied petroleum gas sensing

Bandara, K.N.D.; Jayathilaka, K.M.D.C.; Gunewardene, M. S.; Dissanayake, D.P; Jayanetti, J. K. D. S. (2017)

The surface of electrodeposited n-Cu2O thin films were modified by sulphidation using aqueous Na2S followed by (NH4)2S vapor treatment. Compared to untreated thin films, the resultant films showed an enhanced response ...
Effects of Surface Modification of n-Cu2O/p-CuxS Thin Film Heterostructures for Enhanced Liquefied Petroleum Gas Sensing Properties

Bandara, K.N.D.; Jayathilaka, K.M.D.C.; Gunewardene, M. S.; Dissanayake, D.P.; Jayanetti, J. K. D. S. (2016)

We report a novel mechanism to effectively detect LP gas based on surface modification through sulphidation followed by passivation of electrodeposited n-type cuprous oxide (Cu2O), forming a thin film n Cu2O/p-CuxS ...
Nanoporous Cu2O nanotube/nanorod array electrodes for non-enzymatic glucose sensing with high sensitivity and very low detection limit

Jayasingha, Lakmini; Jayathilaka, Charith; Kumara, Roshantha; Ohara, Koji; Kaumal, Migelhewa; Gunewardene, Siyath; Dissanayake, Dhammike; Jayanetti, J. K. D. S. (2020)

This study compares the non-enzymatic glucose sensing performance by Cu2O nanorods/nanotubes grown using electrochemically anodized Cu foam and Cu plates to form binder free one-dimensional Cu(OH)2 nanostructures which ...
Surface engineering of electrodeposited cuprous oxide (Cu2O) thin films: Effect on hydrophobicity and LP gas sensing

Bandara, K.N.D.; Jayathilaka, K.M.D.C.; Dissanayake, D.P.; Jayanetti, J. K. D. S. (2021)

P-type cuprous oxide thin films electrodeposited on a titanium substrate in a lactate bath was investigated for liquid petroleum gas (LPG) sensing. Contact angle measurements using water droplets revealed that the surfaces ...
Ammonium Sulfide Surface Treatment of Electrodeposited p-Type Cuprous Oxide Thin Films.

Jayathilaka, K.M.D.C.; Siripala, W.; Kapaklis, V; Jayanetti, J. K. D. S. (2014)
